Resumen del manual
When not using the unit, you should disconnect any cord connected to the INPUT Jack. 5 LEVEL Knob I ENHANCE Knob THRESHOLD Knob LEVEL Xnob This knob adjusts the level of the effect sounds. Set the knob so there is no volume difference between the effect and straight guitar sounds. * If this knob is rotated completely counterclockwise, no sound will be heard. ENHANCE Knob This knob adjusts the intensity of the enhance effect that makes the sound clearer and sharper. Rotating the knob clockwise emphasizes the effect. RATIO Knob This knob controls the compression ratio of the limiter. That is, it adjusts how much the limiter should compress those signals above the threshold level. * When it is set to "1:1", no limiter effect will be obtained. THRESHOLD Knob This knob controls the threshold level (the level at which the compression effect will kick in). Rotating the knob counterclockwise lowers the threshold level. For a detailed explanation about the Ratio and Threshold Level, see "ABOUT THE LIMITER'S ACTION". MAKING THE CONNECTIONS * Inserting a plug into the Input Jack will automatically switch the unit on. * Before connecting or disconnecting any patch cords, be sure all the volume controls in your system are set to minimum. This will help prevent any damage to system components. OPERATING THE UNIT 1. When you have made the necessary connections, set the knobs as shown in the illustration. 2. Depress the pedal switch to turn the effect on. (Make sure that the CHECK Indicator lights.) 3. Adjust the Threshold Level (the level at which compression starts) using the THRESHOLD Knob. 4. Adjust the compression ratio using the RATIO Knob. 5. Adjust the intensity of the enhance effect using the ENHANCE Knob. 6. Adjust the LEVEL Knob so there will be no volume difference between the effect and straight bass sounds. 8 ABOUT THE LIMITER S ACTION The LMB-3's limiter will function differently depending upon how you set the Ratio and Threshold Levels. The RATIO and THRESHOLD knobs work as described below. RATIO: The compression ratio for the input signal is called Ratio. For instance, when the Ratio is set to "2:1", an input signal that is 6 dB louder than the Threshold Level will be compressed to one half, or 3 dB When it is set to "°o:l", any input signal above the Threshold Level will be compressed to the Threshold Level, then output. THRESHOLD : The Threshold Level is the level at which compression starts to work. When the input signal has reached the Threshold Level, the signal will be compressed at the compression ratio set with "RATIO", then output. When the input signal is lower than the Threshold Level, it will be output without compression.

Replace the battery following the steps below. 1. Loosen the thumbscrew at the front of the pedal, then lift the pedal upwards to open the unit. * The thumbscrew can be left in the pedal while changing the battery. 2. Remove the old battery from the battery housing, and remove the snap cord connected to it. 3. Connect the snap cord to the new battery, and place the battery inside the battery housing. * Be sure to carefully observe the battery+s polarity (+ versus -). 4. Slip the coil spring onto the spring base on the back of the pedal, then close the pedal. * Carefully avoid getting the snap cord caught in the coil spring. 5. Finally, insert the thumbscrew into the guide bush hole and fasten it securely. 11 SAMPLE SETTING Limiter Enhancer CHECK O LEVEL ENHANCE RATIO THSHD DOOC • • • • • • • - MIN MAX MIN MAX 1:1 °ort MIN MAX Finger Picking CHECK O LEVEL ENHANCE RATIO THSHD DOO MIN MAX MIN MAX 1D °orl MIN MAX 12 CHECK O LEVEL ENHANCE RATIO THSHD DOOO MIN MAX MIN MAX 1:1 °°:1 MIN MAX Slapping Play CHECK O LEVEL ENHANCE RATIO THSHD DOCK MIN MAX MIN MAX 1:1 °°:1 MIN MAX SETTING MEMO CHECK O LEVEL ENHANCE RATIO THSHD _ oo _ • • • • # • • • MIN MAX MIN MAX 1:1 °°:1 MIN MAX CHECK O LEVEL ENHANCE RATIO THSHD OO • • • • • • MIN MAX MIN MAX 1:1 oorl MIN MAX CHECK O LEVEL ENHANCE RATIO THSHD OO _ •> . • • • • MIN MAX MIN MAX 1:1 °°:1 MIN MAX CHECK O LEVEL ENHANCE RATIO THSHD OO • •• • • • MIN MAX MIN MAX 1:1 °o:1 MIN MAX SPECIFICATIONS LMB-3 : Bass Limiter Enhancer Nominal Input Level .................-20 dBm Input Impedance.......................1 MQ Nominal Output Level ..............-20 dBm Output Impedance....................1 kQ Recommended Load Impedance... 10 kQ or greater Residual Noise Level.................-86 dBm (IHF-A, Typ.)
